To all whom it may concern,

3e it known that I, Roam IE. V. AN- cansios, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain Improvements in Suppositories, of which the following is a specific: tion.

The objects of this invention are to produce a suppository with an inclosing cover or shell; to form the body portion of the suppository by means of said cover or shell, without the necessity of touching the ingreclients with the fingers; to thus enable each suppository to be made up under pert'ect sanitary conditions; to avoid the use of any machinery or appliances other than said cover or shell in making up the suppository; to thus enable the suppositories to be made very cheaply; to save time in filling prescriptions for suppositories and to enable them to be made all of the same shape and size; to provide means for readily and conveniently removing the shell or cover when it is desired to administer the suppository to a patient; to insure that the suppository be kept clean and fresh until used, and to obtainether advantages and results as may be brought out in the following descript-ion.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views, Figure 1 is an elevation of the cover or shell of my improved suppository without its cap or top; Fig. 2 is a similar elevation of the cap; Fig. 3 is a sectional view on line AA of Fig. 1 looking in the direction indicated by the arrow; Fig. 4: is a view in perspective showing the method of filling the shell without touching the substance or material containing the medicinal preparation; Fig. 5 is an elevation of the suppository complet as made up by the druggist; Fig. (3 is a perspective view illustrating the removal of the shell or cover prepa artery to administering the suppository, and Fig. 7 is a perspective view of the body portion of the suppository and the shell or cover as removed therefrom.

In the specific embodiment of the inven' tion illustrated in said drawings, the referencenumeral 1 indicates a shell of any material suitable for the purpose, such as gelatin, and of the common and well-known conical shape of a suppository, with its base or large end open. Extending along the inner surface of the wall of said shall 1, and preferably embedded or partially embedded therein, is a rip-st ring 2, and preferably this string extends from a point at. the open end edge of the shell longitudinally to the apex and then back again to the open end edge along the opposite side of the interior chamber or cavity of the shell, as shown in Fig. 3. lloth of the ends 3, -t of the rip-string may hang out over the edge of the shell, as shown in the drawings, or it preferred one of them may be cut oll rlosc to the edge.

It will be seen from the further description of the invention herein that the exact arrangement and disposition of the ripstring upon the inner wall of the shell could be varied considerably, so long asit was adapted to accomplish the purposes set 'lorth.

In making suppositories according to my invention, the druggist places the coca but:- ter or other equivalent material containing the medicinal preparation upon a suitable surface. as shown at 5 in Fig. l, and then takes the shell 1 in his fingers holding it inverted and with the ends 3, 4; of the ripstring caught back out of the way. By pressing the shell down into the material before him, repeatedly, the shell is filled, and its contents are more or less compact and solid according to the length of time he continues this process and the pressure he uses. It will be understood that so much of the substance as goes into the shell at each downpressing of the same sticks there, especially at the right temperature, and that the entrance of each additional portion forces previous portions up the shell toward its apex. In this way, by continuing the process long enough and using sullicient pressure, a com pact body portion 6 can be easily and very quickly formed inside the shell.

It is to be noted that the hands of the druggist in filling the shell have no occasion to touch the mixture, so that possibility of contamination is avoided. I urthermore, it is to be understood that in filling a certain prescription only a sullicicnt amount of mixture is compounded to tilt the prescribed number of shells and thus any waste in preparing the suppositories is avoided. The filling can also be done quickly and neatly. \Vhen a shell has been thus filled, a cap 7 is slipped over its open end, so as to entirely inclose the body portion (3 of the suppository from exposure or contact with any object whereby infection might be inadvertently carried to the user. This top or cap 7 I have shown as cylindrical in shape, frictionally fitting around the shell adjacent its open end, although it is deemed within the scope of the appended claims to form this cap in any shape desired. lit will be understood that the ends 3, l of the rip-string do not interfere with putting on this cap 7, preferably extending between it and the shelland projecting alongside the shell toward its apex, as shown in Fig. 5. In this condition, my improved suppository can be kept for a considerable time without any drying up or deteriorating, and can also be conveniently and safely handled.

hen the suppository is to be used, the cap 7 is first removed and thrown away, and then the rest of the suppository is immersed in water for a minute or two so as to soften the shell 1. hen taken out of the water, with the shell properly softened, the ripstring 2 will tear its way through the shell, upon being pulled or drawn, so as to divide the shell into two parts or halves 8, 8 which can be readily detached from the body por tion 6, as shown in Fig. 7. I have illustrated in Fig. 6 a convenient way of holding the suppository in one hand and pulling the rip string 2, first by one end 3 and then by the other end 4, or if preferred the pulling may all be done upon one and the same end of the rip-string, but obviously said rip string may be utilized in any manner de sired to properly tear the shell 1 so that it can be separated from the body portion 6.

The purpose of my invention is to remove the shell 1 from the body portion 6 with a minimum amount of diflioulty and handling,

so that said body portion can be administered to the patient and the shell and ripstring thrown away, and I desire it to. be understood as within the scope of the invention that any suitable means for accomplishing this can be employed, those shown in the drawing being merely illustrative.

Having thus described the invention, what I claim is 1. A suppository comprising a shell, a body portion in said shell, a removable closure for said shell, and means for ripping said shell to disengage it from said body portion.

2. A suppository comprising a shell, a body portion in said shell, a closure for said shell, and a rip string for said shell adapted to rip the same apart when said closure is removed.

A suppository comprising a shell, a body portion in said shell, and a rip-string upon the inner surface of said shell projecting outside the same.

4. A suppository comprising a shell, a body portion in said shell, and a rip-string partially embedded in the inner wall of said shell having one end projecting outside said shell.

5. A suppository comprising a shell, a body portion in said shell, a rip-string upon the inner surface of said shell projecting outside the same, and a cap closing said shell, and confining the ends of said ripstring.
